This research investigated compounds produced by a fungus found living in association with marine sponges. The scientists discovered several new chemical compounds that could help fight bacterial infections, particularly by preventing bacteria from forming protective biofilms. This work is important because it demonstrates how marine organisms can be sources of new medicines. Impacts on everyday life: • Provides potential new ways to fight antibiotic-resistant bacterial infections • Demonstrates the importance of preserving marine biodiversity as a source of new medicines • Offers possible alternatives to current antibiotics that bacteria have become resistant to • Could lead to new treatments for preventing bacterial biofilm formation in medical devices and implants
